RESUMEN
BACKGROUND: Coronavirus disease 2019 (COVID-19) is still an ongoing entity and every day we face new sequalae of the disease. We hereby present surgical results of patients who are treated for post-COVID chronic thromboembolic pulmonary hypertension. METHODS: Data were collected among patients who underwent pulmonary endarterectomy and had a diagnosis of post-COVID chronic thromboembolic pulmonary hypertension. All data were retrospectively reviewed from a prospectively conducted database. Operative mortality was described as death in hospital or within 30 days of surgery. RESULTS: Eleven patients (seven males, four females; median age, 52 [22-63] years) were identified. Pulmonary vascular resistance improved significantly from 572 dyn/s/cm-5 (240-1,192) to 240 (195-377) dyn/s/cm-5 (p < 0.005). Significant difference was also detected in median mPAP, as it decreased from 40 mm Hg (24-54) to 24 mm Hg (15-36) following surgery (p < 0.005). Mortality was observed in one patient due to sepsis on the fifth postoperative day. Median time from COVID-19 disease to surgery was 12 months (6-24). Median length of hospital stay of the survivors was 10 days (8-14). CONCLUSION: In the new era of chronic thromboembolic pulmonary hypertension, hybrid approach including surgery, balloon pulmonary angioplasty, and medical treatment has been recommended. pulmonary endarterectomy is still the only curative treatment when the disease is surgically accessible. We hereby report the first publication of post-COVID chronic thromboembolic pulmonary hypertension patients who were surgically treated. As we see a lot of long-term symptoms and clinical manifestations in patients who had COVID-19, we should always remember chronic thromboembolic pulmonary hypertension in the differential diagnosis.

AIM: The aim of the present study was to evaluate the value of electrocardiography (ECG) in predicting postoperative hemodynamic improvement in patients with chronic thromboembolic pulmonary hypertension (CTEPH) undergoing balloon pulmonary angioplasty (BPA). MATERIAL AND METHODS: A total of 32 patients were included in the study. During ECG analysis, parameters that have been suggested to be related to right ventricular hypertrophy and/or dilatation were evaluated. The significance of the change in each parameter obtained at the pre-BPA visit and at the scheduled control visit 6 months after BPA was tested. In addition to ECG analysis, data related to right heart catheterization (RHC) and echocardiography, B-type natriuretic peptide (BNP) levels and World Health Organization (WHO) functional classifications of all patients were also recorded. The relationship between the amount of possible change in ECG parameters and the amount of possible change in hemodynamic parameters was investigated. RESULTS: The Daniel score, which has been suggested to have prognostic value in acute pulmonary embolism, decreased from 8.22 ± 5.68 to 6.56 ± 5.55 after the BPA procedure (p: 0.035). Among all parameters studied, only T wave height (V2 t) in V2 derivation changed significantly from -0.77 ± 2.39 to 1.27 ± 2.58 mm (p: 0.036). The amount of change in V2 T was found to significantly correlate with the amount of change in systolic right ventricular pressure, mean pulmonary artery pressure, pulmonary vascular resistance, and systemic vascular resistance. CONCLUSION: Postprocedural T wave changes in lead V2 might serve as a marker of hemodynamic improvement in patients with CTEPH who undergo BPA.

PURPOSE: High mortality and a limited performance of valvular surgery are typical features of infective endocarditis (IE) in octogenarians, even though surgical treatment is a major determinant of a successful outcome in IE. METHODS: Data from the prospective multicentre ESC EORP EURO-ENDO registry were used to assess the prognostic role of valvular surgery depending on age. RESULTS: As compared to < 80 yo patients, ≥ 80 yo had lower rates of theoretical indication for valvular surgery (49.1% vs. 60.3%, p < 0.001), of surgery performed (37.0% vs. 75.5%, p < 0.001), and a higher in-hospital (25.9% vs. 15.8%, p < 0.001) and 1-year mortality (41.3% vs. 22.2%, p < 0.001). By multivariable analysis, age per se was not predictive of 1-year mortality, but lack of surgical procedures when indicated was strongly predictive (HR 2.98 [2.43-3.66]). By propensity analysis, 304 ≥ 80 yo were matched to 608 < 80 yo patients. Propensity analysis confirmed the lower rate of indication for valvular surgery (51.3% vs. 57.2%, p = 0.031) and of surgery performed (35.3% vs. 68.4%, p < 0.0001) in ≥ 80 yo. Overall mortality remained higher in ≥ 80 yo (in-hospital: HR 1.50[1.06-2.13], p = 0.0210; 1-yr: HR 1.58[1.21-2.05], p = 0.0006), but was not different from that of < 80 yo among those who had surgery (in-hospital: 19.7% vs. 20.0%, p = 0.4236; 1-year: 27.3% vs. 25.5%, p = 0.7176). CONCLUSION: Although mortality rates are consistently higher in ≥ 80 yo patients than in < 80 yo patients in the general population, mortality of surgery in ≥ 80 yo is similar to < 80 yo after matching patients. These results confirm the importance of a better recognition of surgical indication and of an increased performance of surgery in ≥ 80 yo patients.

BACKGROUND: Patients with inoperable chronic thromboembolic pulmonary hypertension (CTEPH) are often treated with pulmonary arterial hypertension-specific drugs. However, most of these patients remain symptomatic, despite medical treatment. Balloon pulmonary angioplasty (BPA) is an emerging therapeutic intervention for patients with inoperable CTEPH. This study aimed to report the initial experience of BPA in a tertiary referral centre for CTEPH. METHODS: A total of 26 consecutive patients, who underwent 91 BPA sessions, were included in the study. All patients underwent a detailed examination, including 6-minute walking distance (6MWD), and right heart catheterisation at baseline and 3 months after the last BPA session. RESULTS: The mean age of the patients was 51±17 years. Fifteen (15) patients had inoperable CTEPH and 11 patients had residual or recurrent CTEPH post pulmonary endarterectomy (PEA). Functional class improved in 17 of 26 (65%) patients. The 6MWD increased from a mean 315±129 to 411±140 m (p<0.001), and NT pro-BNP reduced from a median 456 to 189 pg/mL (p=0.001). The number of patients who required supplemental oxygen decreased from 11 (42.3%) to five (19%) (p=0.031) after BPA treatment. The mean pulmonary artery pressure decreased from a mean 47.5±13.4 to 38±10.9 mmHg (p<0.001), the pulmonary vascular resistance decreased from a mean 9.3±4.7 to 5.8±2.8 Wood units (p<0.001), and the cardiac index increased from a mean 2.4±0.7 to 2.9±0.6 L/min/m2 (p=0.008). CONCLUSIONS: Balloon pulmonary angioplasty improved haemodynamics, 6MWD, and functional class, and reduced the requirement for supplemental oxygen, with an acceptable risk-benefit ratio in patients with inoperable CTEPH and with residual/recurrent CTEPH.

BACKGROUND: Chronic thromboembolic pulmonary hypertension (CTEPH) is a form of pulmonary embolism, and pulmonary endarterectomy (PEA) is the surgical treatment. Asymmetric dimethylarginine (ADMA) levels are increased in pulmonary hypertension. This study aimed to investigate serum ADMA levels in patients with CTEPH, the effect of PEA on ADMA, and its prognostic value in long-term mortality. METHOD: Eighty (80) patients with CTEPH and 32 healthy controls were included. Preoperative serum ADMA levels, determined using an enzyme-linked immunosorbent assay, were compared between patients with CTEPH and controls. Of 80 patients, 64 had PEA. Pre- and 6-month postoperative serum ADMA levels, 6-minute walk distance (6MWD), and haemodynamic parameters were collected from patients undergoing PEA. Patients were followed-up for survival analysis. RESULTS: Mean ± standard deviation serum ADMA levels were significantly higher in patients with CTEPH compared with controls (0.79±0.32 µmol/L vs 0.52±0.12 µmol/L; p=0.0001). Statistically significant differences were observed between preoperative and postoperative serum ADMA levels (0.78±0.30 µmol/L vs 0.62±0.22 µmol/L; p=0.0001), 6MWD (p=0.0001), and pulmonary vascular resistance (p=0.0001) in 60 patients who underwent and survived PEA. The decrease in serum ADMA levels and increase in 6MWD were significantly correlated (r=-0.286, p=0.027). No other correlation was found. Perioperative mortality was 6.3%, and the survival rate with a mean follow-up of 34.57±8.20 months was 93.3%. Patients with serum ADMA levels >0.8 µmol/L had a significantly lower survival rate (logrank: 5.86; p=0.015). CONCLUSIONS: Levels of circulating ADMA might add diagnostic and prognostic information in CTEPH. Pulmonary endarterectomy is associated with an improvement in serum ADMA levels. Preoperative serum ADMA levels may be useful for estimating the outcome of PEA.

Skeletal and respiratory muscle dysfunction has been previously described in patients with other etiologic subgroups of pulmonary arterial hypertension (PAH) but has never been investigated in patients with PAH due to congenital heart diseases (CHD). This study aims to show the involvement of skeletal and respiratory muscles in these patients. This cross-sectional study included patients with PAH due to CHD and healthy controls. Patients' demographic properties, six-minute walk tests; shoulder abduction, handgrip, knee extension, and ankle dorsiflexion muscle strength, maximum inspiratory (MIP) and expiratory pressures (MEP) were measured. Deltoid, flexor digitorum superficialis, and profundus, tibialis anterior and rectus femoris muscles were visualized with ultrasonography and their cross-sectional areas (CSA) were also measured in both groups. 12 patients and 12 controls were included. Mean MIP was 104.22±32.57 cm H2O for healthy participants while 61.33±29.74 cm H2O for patients (p<0.001). For mean MEP, it was 100.08±26.05 cm H2O in healthy participants and 69.75±39.79 cmH2O in controls (p=0.004). When the strength of skeletal muscles was compared, there were significant differences between the groups in all measurements except for bilateral grip strength. In the correlation analysis, MIP and MEP values showed no significant correlations with clinical parameters. They showed significant moderate correlations with skeletal muscle strength. When CSAs of the muscles were compared, there were significant differences in all measurements except for left FDS and FDP and bilateral rectus femoris. This study showed that in patients with pulmonary arterial hypertension due to CHD, respiratory muscle strength is significantly worse than healthy participants. Patients had also significantly worse skeletal muscle strength except for grip strength.

PURPOSE: Right ventricular (RV) function is an important factor in the prognosis of chronic thromboembolic pulmonary hypertension (CTEPH) in patients. In our study, we aimed to evaluate the timing and magnitude of regional RV function before and after balloon pulmonary angioplasty (BPA) using speckle tracking echocardiography (STE) and their relation to clinical and hemodynamic parameters in patients with CTEPH. MATERIAL AND METHOD: We enrolled 20 CTEPH patients and 19 healthy subjects in our study. Enrolled patients underwent echocardiography, right heart catheterization (RHC), and 6-minute walk distance (6MWD) test at baseline and after the BPA. RESULTS: In hemodynamic RHC measurements and clinical evaluations, mean pulmonary artery pressure (median: 53.5 mm Hg vs 37.0 mm Hg, P = .001) and pulmonary vascular resistance (median: 12 Wood units [WU] vs 7 WU, P = .001) and pro-brain natriuretic peptide level decreased and 6MWD increased after BPA sessions. There was no statistically significant difference between before and after the BPA sessions in conventional echocardiographic measurements. In STE analysis, the electromechanical delay (EMD) between RV free wall (RVF) and LV lateral wall (LVL) (median: 65 ms vs 47.5 ms, P = .01) and RV peak systolic strain dispersion index (52 ms vs 29 ms, P = .001) were higher in patients with CTEPH than healthy controls before the BPA. Both these parameters decreased significantly after BPA. CONCLUSION: Chronic thromboembolic pulmonary hypertension was associated with RV electromechanical delay and dispersion based on the STE analysis. Balloon pulmonary angioplasty might have an important impact on the improvement of both RV function and hemodynamics.

PURPOSE: Right ventricular (RV) dysfunction is a common condition that is related to increased adverse outcomes in patients with acute pulmonary embolism (APE). Our aim was to assess timing and magnitude of regional RV function using speckle tracking echocardiography (STE) and to evaluate their relationship to long-term mortality in patients after APE. METHODS: In total, 147 patients were enrolled at the onset of an APE episode and followed for 12 ± 1.1 months. For all patients, the clinical, laboratory, and echocardiography examinations were performed at the diagnosis of APE and at the end of the 1-year follow-up. RESULTS: Of the 147 patients, 44 (29.9%) died during the 1-year follow-up after APE. The patients who died had lower RV free wall peak longitudinal systolic strains (PLSS) and left ventricular (LV) PLSS and higher RV peak systolic strain dispersion (PSSD) index which means the electromechanical dispersion when compared with the survivors. The difference in time to PLSS between the RV free wall and LV lateral wall (RVF-LVL) which means the electromechanical delay was longer in patients who died than in those who survived during follow-up, and this difference was an independent predictor of mortality at 1 year of follow-up after APE, with 86.4% sensitivity and 81.7% specificity. At the end of 1-year follow-up, the RV free wall PLSS and the LV global PLSS increased, whereas the RV PSSD index and the difference in time to PLSS between the RVF and LVL decreased. CONCLUSIONS: Acute pulmonary embolism was associated with RV dysfunction and RV electromechanical delay and dispersion. These parameters improved at the end of 1-year follow-up. The electromechanical delay index might be a useful predictor of mortality in patients after APE.

AIMS: To reduce the risk of inadvertent arterial puncture and bleeding, we aimed to define a safe puncture site by demonstrating the relation of the axillary artery and vein. METHODS: The anatomical course and relation as well as crossover sites of the axillary artery and vein, the presence of small arterial bridges over the axillary vein, and validation of commonly preferred axillary venous puncture sites were determined by simultaneous ipsilateral venography in patients (n = 111; 80 men, age 60 ± 10 years) who underwent coronary angiography by radial artery access. RESULTS: The axillary vein was detected at the first costa-clavicular intersection in 62% and at the second anterior and third posterior costal intersection in 60% of the patients. Small arterial bridges over the axillary vein were observed in 77% of the patients and more frequently in females and body mass index ≥25 kg/m2 (P = 0.034 and P = 0.03, respectively). The axillary artery crossed the vein in 24% of the patients and almost always within the region close to the first costa-clavicular intersection site. CONCLUSION: Our study demonstrated a high crossover rate (24%) of axillary artery and vein and a high degree of variation in the course of axillary vein. Small arterial bridges over the axillary vein were observed in 77% of the patients.
RESUMEN
BACKGROUND: Our aim was to determine the prevalence of coronary artery - pulmonary artery collaterals in patients with chronic thromboembolic pulmonary hypertension (CTEPH) by retrospectively evaluating coronary angiograms of eligible consecutive patients who had undergone pulmonary endarterectomy (PEA). We also aimed to evaluate predictors and potential clinical associates of these collaterals. METHODS: Coronary angiograms of 83 consecutive CTEPH patients who had undergone coronary angiography before PEA operation between January 1, 2012 and June 1, 2015 were retrospectively evaluated for presence of coronary artery - pulmonary artery collaterals. Medical records of all patients were also retrospectively reviewed for demographic information, cardiovascular risk factors, preoperative right heart catheterization reports, operation reports, and follow-up data. Data of CTEPH patients with coronary artery - pulmonary artery collaterals were compared with data of CTEPH patients without such collaterals. RESULTS: There were 15 patients (18.1%) with definite and 4 patients (4.8%) with probable coronary artery - pulmonary artery collaterals among the study population. CTEPH patients with collaterals had higher preoperative pulmonary artery pressures, higher pulmonary vascular resistance (PVR) and lower cardiac index values compared with CTEPH patients without collaterals. However, CTEPH patients with collaterals displayed higher amount of reduction in PVR after PEA compared with patients without collaterals. There were no significant differences between groups regarding incidence of reperfusion injury or mortality. CONCLUSION: Prevalence of coronary artery - pulmonary artery collaterals seems to be increased in our CTEPH patients compared with the general population. The presence of coronary artery - pulmonary artery collaterals is often combined with proximal disease with the possibility of increased reduction of PVR after PEA operation.

BACKGROUND: Behçet's syndrome (BS) is a multisystem disorder and is not known as a risk factor for chronic thromboembolic pulmonary hypertension (CTEPH), for which the treatment of choice is pulmonary endarterectomy (PEA). The aim of this study was to review our experience in the surgical treatment of CTEPH in patients with BS. METHODS: Data were collected prospectively for consecutive patients with BS who underwent PEA over a 6-year period. RESULTS: We identified nine patients (seven males, two females, mean age: 34.7 ± 9.9 years) with BS. The mean disease duration before PEA was 88.0 ± 70.2 months. All patients but one received immunosuppressive therapy before the surgery. Exercise-induced dyspnea presented symptoms in six patients. One patient had associated intracardiac thrombosis. PEA was bilateral in five patients, unilateral in three, and lobar in one. No perioperative mortality was observed; however, one patient died four weeks after PEA due to massive hemoptysis. Morbidity was observed in two patients. The systolic pulmonary artery pressure fell significantly from 59.0 ± 22.7 mm Hg to 30.0 ± 6.5 mm Hg after surgery (p = 0.031). Pulmonary vascular resistance also improved significantly from 611.8 ± 300.2 to 234.7 ± 94.9 dyn/s/cm5 (p = 0.031). After a median follow-up of 29.4 months, all patients improved to the New York Heart Association (NYHA) functional class I and II. CONCLUSION: Patients with BS may suffer recurrent pulmonary embolism and develop CTEPH. In patients who do not respond to anticoagulation or immunosuppressive therapy, PEA may be a therapeutic option when thrombotic lesions are surgically accessible. Due to the high risk of perioperative mortality, the procedure should be undertaken in centers with experience.

Objective The frequency, significance and prognostic value of left ventricle obstruction (LVO) induced with provocation (latent LVO) is controversial for hypertrophic cardiomyopathy (HC) patients. This study was designed to assess the value of latent LVO in predicting the clinical course in 101 patients with HC. Methods and results Patients were followed for a mean of 82 ± 48 months (range 2 to 148 months) for clinical end points defined as a composite of cardiovascular death resuscitated cardiac arrest, appropriate defibrillator shock or hospitalization due to worsening of heart failure symptoms. Presence of LVO (hazard ratio 3.63; 95% confidence interval, 1.85 to 7.12; P = 0.0001) and log NT-proBNP levels (hazard ratio, 1.40; 95% confidence interval, 1.14 to 1.72; P = 0.001) were the independent variables associated with an increased risk of experiencing clinical end points. HC patients with latent LVO have a trend toward decreased survival when compared with HC patients without LVO (log rank P = 0.027), but better survival than patients with resting LVO (log rank P = 0.007). HC patients with NT-proBNP levels <1,000 pg/ml had also better survival. LVO and NT-proBNP levels are the major determinants of clinical end points in patients with HC. Conclusions Evaluation of patients without resting LVO to demonstrate latent obstruction is of critical importance in respect of outcome and selection of patients for septal reduction therapies, so routine provocative testing with physiological exercise and measurement of NT-proBNP is recommended in this patient population for risk stratification.

Riociguat is a new drug prescribed to patients with pulmonary hypertension that reduces the pressure in pulmonary artery by vasodilation. This drug like many other drugs has several side effects, some of which can be serious such as bleeding. Riociguat causes vaginal bleeding by increasing endometrial thickness and blood flow to the endometrium, therefore, should be used with care especially for patients who have history of dysfunctional uterine bleeding. In this case report, we present a 27-year-old female patient with chronic thromboembolic pulmonary hypertension and dysfunctional uterine bleeding presented with severe vaginal bleeding under riociguat treatment.

Atrial fibrillation (AF) is an important risk factor for cardioembolic stroke. Warfarin is an effective treatment in reducing the risk of cardioembolic stroke in patients with AF. New anticoagulants have been widely using for stroke prophylaxis in patients with nonvalvular AF. Previous studies have suggested that thrombolytic therapy is effective treatment choice in patients with pulmonary embolisms. Warfarin therapy is also effective on prevention or treatment of cardiac thrombus in patients with AF. However, there are no evidence-based data on treatment of cardiac thrombus with new oral anticoagulants in patients with AF. In our case report, we reported an AF patient with cardiac thrombus and pulmonary embolism under dabigatran therapy.

Pulmonary embolism is a frequent and mortal situation especially in high-risk patients. Although thrombolytics and anticoagulants are the main options in treatment, substantial portion of patients also have high bleeding risk. Therefore, new catheter-directed treatment strategies, such as ultrasound-assisted transcatheter thrombolysis, gain importance in treatment options for intermediate and high-risk patients. Here, we report a case of massive pulmonary embolism due to the iatrogenic lymphocele after a radical retropubic prostatectomy procedure. The usage of ultrasound-assisted transcatheter thrombolysis was successful in such a high-risk patient.

BACKGROUND: The study evaluates the alterations in exercise capacity of chronic thromboembolic pulmonary hypertension (CTEPH) patients after pulmonary endarterectomy (PEA) and investigates the echocardiographic parameters associated with the degree of functional recovery. METHODS: Thirty consecutive patients with the diagnosis of CTEPH (17 males; mean age, 45.9 ± 15.1 years) who had been referred for PEA operation were included in the study. Each patient underwent transthoracic echocardiography and 6-minute walk test (6-MWT) before and 6 months after PEA. RESULTS: After PEA, 6-MWT distances significantly increased (242.8 ± 112.8 m vs. 423.6 ± 89.1 m, p < 0.001), whereas systolic pulmonary artery pressures and right ventricular dimensions significantly decreased (86 ± 25.1 mm Hg vs. 41.9 ± 15.6 mm Hg, p < 0.001 and 42.1 ± 10.1 mm vs. 35.3 ± 5.6 mm, p < 0.001, respectively). Magnitude of change in 6-MWT distance (Δ-6-MWT) was found to be correlated with concomitant change in tricuspid annular plane systolic excursion and left ventricular myocardial performance index (r: 0.518, p: 0.004 and r: -0.385, p: 0.043, respectively). Linear regression analysis revealed preoperative 6-MWT distance as an independent negative predictor of delta-6-MWT (beta: -0.89, t: -3.97, p: 0.001). CONCLUSION: CTEPH patients with more severely depressed exercise capacity at baseline displayed relatively greater degree of functional recovery after PEA in our study. Improvement in functional capacity was found to be correlated with improvement in parameters reflecting right ventricular functions rather than improvement in pulmonary artery pressure after PEA operation.

Although current pulmonary hypertension (PH) guidelines recommend a pulmonary capillary wedge pressure (PCWP) >15 mm Hg for the detection of a postcapillary component, the rationale of this recommendation may not be quite compatible with the peculiar hemodynamics of PH. We hypothesize that a high PCWP alone does not necessarily indicate left-sided disease, and this diagnosis can be improved using left ventricle transmural pressure difference (∆ PTM). In this 2-center, retrospective, observational study, we enrolled 1,070 patients with PH who underwent heart catheterization, with the final study population comprising 961 cases. ∆ PTM was calculated as PCWP minus right atrial pressure. The patients with group II PH had significantly higher ∆ PTM values (12.6 ± 6.6 mm Hg) compared with the other groups (1.1 ± 4.8 in group I, 12.4 ± 6.6 in group II, 2.5 ± 6.4 in group III, and 0.8 ± 8.0 in group IV, p <0.001) despite overlapping PCWP values. A ∆ PTM cutoff of 7 mm Hg identifies left heart disease when PCWP is >15 (area under curve 0.825, 95% confidence interval 0.784 to 0.866, p <0.001). Five-year mortality was significantly higher in patients with high ∆ PTM and PCWP subgroups compared with low ∆ PTM plus high PCWP (26.1% vs 18.5%, p = 0.027) and low ∆ PTM and PCWP subgroups (26.1% vs 15.6%, p <0.001). ∆ PTM has supplementary discriminatory power in distinguishing patients with and without postcapillary PH. In conclusion, a new approach utilizing ∆ PTM may improve our understanding of PH pathophysiology and may identify a subpopulation that may potentially benefit from PH-specific treatments.
